You haven't given us any information about what kind of equipment
you are using to impliment the DNS-based ACLs, and we cannot infer
it from your choice of newsgroups.

We -can- infer that you are not using Standard or Extended ACLs
under Cisco IOS or ACLs on a Cisco PIX, as those do not support
acls such as "*.gov". (But you might be using CBAC on Cisco IOS
I guess.)
